All of those answers are good to hear, if a little short on details.
That should get a few more of my friends playing. I am interested to learn more about these tactical challenges mentioned as well.
Iron Domokun, you may be interested to learn that there are also a -number- of scenarios in SFB which may interest you. A quick check shows there are there are, to date, 86 'general' scenarios, 257 'historical', 280 'Captain's Log' (bi-annual magazine published by ADB), 18 'monster', as well as a number of published campaigns of various sizes, and that's not even the full list. More empires and their ships added later will only increase your options.
Also, am I to understand that ACTA is played on a hexless map/board?
